SHEET-DELIVERY APPARATUS FAQR PRlNTlNG-PRESSES.

SPECIFIATION forming part of Letters Patent No. 704,868, dated July 1 5, 1 902. Application led Januaryv 2, 1902. Serial No. 88,187. (No mhnflel.)

To (LZ-Z whom, t indy/concerns Be it known that-I, GEORGE P. FENNER, acitizen of the United States,.residin g at New London, in the county of New London. and State of Connecticut, have invented new and useful Improvements inSheet-Deliv ery Apparatus for Printing-Presses, ofwhiclrthe following is a specification.

This invention relates to an attacliinentgfor delivering the sheet printed side down, if desired; and the invention resides in certain novel features of construction set forth in they following specification and claims and illustrated in the annexed drawings, in which- Figure 1 is a side elevation of a sheet-delivery arrangement embodying vthis invention. Fig. 2 is a detail View of part of Fig. 1

. enlarged, showing the presser-roll out of acl tion or raised, as on the recovery or return stroke. Fig. 3 is a View like Fig. 2, showing the presser-roll in action or pressing onto the feed or curler roll. Fig. 4 is a plan View of Fig. 2. Figs. 5 and 6 show a side and plan View, respectively, of a modified forni.

In the drawings Vis shown a frame or part of a frame or support 1. The impression-cylinder 2 and bed 3 are known in the artpand reqnire no detailed description, Suitable gears 4 drive the rollers about .which run'fthe deliv-' ery-tapes 5. A sheet from cylinder`2 is 'carrie'd by the tapes'onto or-over a table'oringers 6 on reciprocating carriage 7,`ma'de tov travel back and forth along a way ontrack 8.

Any suitable carriage-driverwill reciprocate I the carriage. Theiactuato'r shown, compris-1 ing a carriage-rack engaged by gear 9, driven` by the reciprocating rack 10 and crank'll, has been found satisfactory.

It has been found advisable to apply guides or lingers 12, which prevent theleadingedge of the sheet curling up or rising away from'. the table or board 6.

The Vattaehiiient'for reversing a sheet or delivering the same printed side down is shown l ing edge of the` sheet passes between the cur- '.ler-roller 16 and presser-roller 17, such sheet being fed against the c nrlers will be bent or reversed, so as to land onthe deliyery-board 1S with the face or printed sidevdown.

A rack 19 vis engaged by gear 2O onv the curler-shaft, and as the gear runs back and ,forth on the rack its rotation is communicated to the curler-rollers. On the return stroke of the carriage after a sheet has been delivered the curler gear and roller can rotate backward without objection, as no sheet is between the curler-roller and presser-roller, or, if desired, the gear and curler-roller can have a ratchetand-pawl connection to cause the curler-roller to be rotated in only one direction. Such a ratchet-and-pawl connection is shown at gear 20 in Figs. 2, 3, and 4; but in Figs-5 and 6 the gear 2O is shown without ratchet-and-pawl connection. In the construction of Figs. 5 and 6 the curler-roller rotates backward on the return stroke of ythe carriage.

The presser-roller 17 can be temporarily raised oridlerto allow the leading edge of a sheet to pass readily onto the cnrler-roller 16, after which-the presser-roller can drop or .causethe sheet to be taken or fed between .s'nch presser and cnrler rollers. The presser roller orjdisks 17 4are mounted on arms 21 on the shaft or fulcrumf22,having arm 23, the free'endor roller of whichwhen riding or resting on the high part of the rail or :incline 24 'holds the roller or drop-wheels 17 idle or raised .from the curler-roller.

When not to be used, the curling attachmentcan be put out of action or removed.

In Figs. 5 and 6 the curlers 15, or rather their Asupport or cross-bar 15', are shown mounted'in slotted seats or arms 27, from which seat these cnrlers or bar can be loosened and lifted out or removed when the'fastenings or nuts 25 are loosened or removed.,A Vhen the cnrlers are removed,jtheroller 16 will deliver the sheets printed side up instead of reversed 9 or printed side down. The curlers 15 can be slipped onto bar 15 and secured or held in suitable adjusted position by fastenings or screws 26. The arm 27 extending upward and forward from the shaft ltof front roller IOG 16, the curler 15 is in position to clasp the upper and lower front portion of said roller.

The carriage top or table 5 is shown in form of fingers; but could be otherwise shapedas, for example, in shape of a board.

What I claim as new, and desire to secure by Letters Patent, is-

1. A reciprocating carriage having a shaft, a curler and curler-roll mounted on the shaft, a driving-gear and rack for the curler-roll, a presser-roll, a supporting-arm for the presserroll mounted on the carriage, and a liftingarm and incline for the presser-roll substantially as described.

2. A delivery-tape, a reciprocating carriage made to take a sheet from the tape, a curlershaft on the carriage, a curler-roll and curler on the shaft, a presser-roll, and a lifting-arm and incline for moving the presser-roll out of action, said presser and curler roll being made to feed a sheet to the curler for reversing or bending down the printed side of the sheet substantially as described.

3. A reciprocating carriage having a shaft with a cur1er,a curIer-roll and curler-roll-driving gear all mounted on said shaft, said curler being removable or dismountable substantially as described.

4. A reciprocating carriage having a shaft with arms extended upward and forward therefrom, a front roller on the shaft, a crossshaft on said arms, a curler on said crossshaft made to clasp the upper and lower front portion of the front roller, and a gear for driving the front roller. p

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

GEORGE P. FENNER.
